Potatoes reproduce by growing sprouts on their surfaces as shown.

When planted, these sprouts grow into new plants. This is an example of

• pollination.

• asexual reproduction.

• fertilization.

• seed production.

An advantage of asexual reproduction is that it does not require fertilization. What advantage do the offspring of sexual reproduction most likely have as a result of fertilization?

• DNA variation may allow survival in a changing environment.

• Unfavorable traits from each parent will be eliminated.

• Traits will be perfectly adapted to the environment.

• DNA will be less varied and therefore more stable.

Some fungi can reproduce either asexually or sexually, resulting in offspring with different characteristics. Sexually produced offspring have

• a complex level of cell organization.

• a number of organelles in each cell.

• a lesser risk of having mutations than asexually produced offspring.

• a combination of genetic material from each parent cell.

A main advantage to organisms that reproduce sexually is

• being able to conserve energy.

• having large numbers of offspring.

• greater genetic diversity.

• longer life spans.
